Fist thing to do is change the transmission fluid and filter. Audi says the transmissions have lifetime fluid, but that's bull - change it first and see if that helps. If not, have the car scanned by a shop and have the chassis codes looked into. If there's a true electrical control problem, there should be at least one code stored (which may not trip the check-engine light).

hi i am dieter
im dave

here is something to try
keep some cold water with you and the next time it happens very quickly get out and pour the water on the crankshaft sensor then restart. If it starts right away without the usual two minutes than you will need to change this sensor. The sensor is easy to find you will see a wiring harness around the crankshaft pulley(the large one at the bottom the basically runs all your accessories like the p/s pump, alternator, water pump). Try to famaliarize yourself as to the location of the sensor first so that you can try to restart it within about 30 seconds.

buy a bottle or two of gas line anti freeze, it absorbs any water that may be in your fuel. add one bottle now and one the next time you fill up. if it is water as i suspect you will notice results almost immediately.
